Introduce MACHINE_CPUARCH. Many different MACHINE_ARCHs will be built from one MACHINE_CPUARCH. This will allow us to move to a more standard MACHINE_ARCH for mips and arm which exist in many different endian variants, and for powerpc where both 32 and 64 bit binaries are generated from the same sources.
